A Healthy Social Life Can Save Your Life, Study Claims
Having mates to grab a beer with or family to call when you’re down isn’t just about feeling good—it’s about staying healthy.
Turns out, a healthy social life is more than just a nice-to-have—it could literally save your life. Having mates to grab a beer with or family to call when you’re down isn’t just about feeling good—it’s about staying healthy. Groundbreaking research from the University of Cambridge and Fudan University shows that meaningful interactions with friends and family can boost your immune system, lower your risk of serious diseases like heart disease and type 2 diabetes, and even help you live longer.
Think of it this way: every chat, every laugh, every shared moment is like a small investment in your health. And this isn’t just feel-good science. These connections help regulate stress hormones, reduce inflammation, and strengthen your body’s defences, turning your social life into a secret weapon for staying fit and well.
Why Loneliness Is a Silent Killer
We’ve long known that social isolation and loneliness can lead to poorer health and early death. But until now, how these relationships affect your body has been a bit of a mystery. This study, published in Nature Human Behaviour, dives into the blood proteins of over 42,000 adults to crack the code.
The Science Behind a Healthy Social Life
Proteins are the body’s workhorses, playing key roles in everything from fighting infections to regulating stress hormones. By analysing the ‘proteomes’ (the entire set of proteins) in blood samples, researchers found 175 proteins linked to social isolation and 26 tied to loneliness. The catch? Many of these proteins overlap, and they’re associated with inflammation, cardiovascular disease, and early death.
Key Findings
- Higher levels of the protein ADM (linked to stress and ‘love hormone’ oxytocin) are associated with smaller brain regions involved in emotions and social processing.
- The protein ASGR1 is connected to higher cholesterol and increased risk of heart disease.
- Other proteins are linked to insulin resistance and atherosclerosis (artery ‘furring’).
Why This Matters
Dr Chun Shen explains: “We know social isolation is bad for health, but this study shows how loneliness directly changes the proteins in our blood.” Professor Barbara Sahakian adds: “With more people feeling lonely, tackling this global health issue is urgent.”
Takeaway
Call your mates, join that club, or go for a coffee with family. Your social life isn’t just about fun—it’s keeping your body and brain in top shape.
